I'm sorry new girl, you seem very nice, but unfortunately there is no room for you in this love story.
Oh, you never know. If the girlfriend goes off to a different university far away, and glasses-girl and boyfriend end up going to the same university, ya never know what might happen, particularly since their interests are more in line with each other than the boyfriend and girlfriend.
But what makes me wonder the most is why didn't girlfriend go with boyfriend to that exhibition? It's not like she couldn't go to Kanazawa any old time, and with her boyfriend to boot. Well, if she did, I guess boyfriend wouldn't have been able to progress his relationship with glasses-girl.
